A fun activity where you put on PFDs (layman; "life jacket"), jump in a rubber raft with little PVC paddles and float down the river....no big deal...until you get flipped over, hit on the head with a rock, hit in the teeth with a paddle, flipped out of the raft, pushed out of the raft, or are simply scared out of your mind and go into fight-or-flight mode with those class 5 rapids coming around the bend.

I was having a fun time whitewater rafting until we hit this class 4 sideways, our raft flipped over, I got sucked into the rapid and popped out about 40 feet away (still holding on to my paddle)...After whitewater rafting (which was a real rush) driving on the beltway doesn't seem so bad.
